Problems solved by technology
If you want to organize the valve control system and the thyristor equipment to form a complete system for equipment joint debugging, it is generally necessary to install various equipment in place on the project site and meet the operating conditions, and it is easy to be affected by the construction period, test conditions and conditions. Restricted by environmental conditions and other factors
In addition, the existing method of testing system performance is often affected by many uncertain factors. There are many devices installed on site and the system is relatively complicated, which increases the complexity of problem analysis and search, which will delay the construction period and It will also cause the problem of increasing the engineering cost
At present, there is no test system that completely and effectively checks the thyristor trigger control loop before conducting field system tests.

The invention discloses a dynamic simulation experimental platform of thyristor trigger control. A voltage regulation device dynamically regulates a working voltage to an expected value and then sends the working voltage to a tested converter valve thyristor device; a voltage acquisition device processes acquired voltage data and then sends the acquired voltage data to a tested upper level control and protection system; the tested upper level control and protection system sends acquired data to a backstage workstation by a network, and the acquired data serves as a synchronous reference voltage for adjusting a firing angle; and a tested thyristor monitoring device controls on-off of the tested converter valve thyristor device according to an instruction of a test valve base electronic device. The experimental platform can detect whether equipment performance and functional logic of the thyristor and a valve control system applied to scientific research and engineering projects in the power electronics field, such as high voltage direct current transmission, static high pressure dynamic reactive power compensation and direct current deicing meet the requirement of system design or not before a field system is tested, and provides a convenient, rapid and effective means for relevant technical research and problem analysis.
